Abstract

Cigarettes include tobacco-containing smokable material wrapped in a low porosity paper wrapper. The smokable material includes an intimate mixture of tobacco extract, pyrolyzed alpha-cellulose, agglomerated calcium carbonate particles, glycerin and carboxymethylcellulose. Such cigarettes yield low levels of incomplete combustion products and generate low levels of visible sidestream smoke.
